concern:

I, CLEMMA R. RANEY, .a the United States, residing at Chlthe county ofCook and State of have invented certain new and usefollowing is a full,clear, and exact specification.

My invention relates to grain shockers.

It has for its object to improve plify the and simconstruction of such amachine.

More specifically it has for its object to improve and simplify thedriving,

controlling and dumping mechanism of a shocker in such a manner as toreduce decrease the cost of the weight thereof and labor and material inmanufacturing, at the same time that a sturdy mechanism is providedwhich is well adapted to withstand long service 1n the eld. I attaintheseobjects by an improved construction and combination of parts inwhich the power is taken from the binder in an improved manne-r throughsimplified mechanism Vand in which the controlling mechanism for thefork'clutch and the shock binding clutch, as well as the dumpingmeehanism for the shock receptacle, is also materially simplified. Theseand other improvements not herein specifically mentioned will be morefully In the forms as hereinafter brought out.

accompanying drawings I have which may assume in practice, and indescription shall refer to these examples of the various embodimentswhich my invention may assume.

In these drawings:

Fig. 7

is a detail view in modified form being used whichis carried on ashocker frame 2 and movable Vby means ofy a resilient pitman connection3 about an axis on a shaft 4 from its sheaf receiving Fig. 1, wherein itrests on a support 5 at a point beneath the deck of the binder, to itssheaf delivering position, wherein it delivers the sheaves in prostrateposition in an upwardly and rearwardly movable shock receptacle 6carrie-d at the rear of the shocker frame. Also, after the manner of theconstruction descr-bed and claimed in my copending application, "SerialNo. 742,535, filed January 17, 1913, when enough sheaves have beendelivered to the shock receptacle G to build a shock therein of apredetermined size, a compressor 7 and needle 8 are thrown intooperation to compress and bind the shock, and at the completion of thecompressing and binding operation, through the rotation of a knottershaft 9, the shock receptacle is moved upward and rearward to depositthe shock in upright position upon the ground.

The fork 1 and all the other mechanisms upon the present shocker aredriven from a longitudinally disposed power shaft 10 which is ofeXtensible and flexible character and is connected between a power chain11 on the binder and a beveled driving gear 12 on the shocker through acoperating beveled gear 13. As shown, the rear end of the shaft'lO-isjournaled on a bracket 15 on the shocker frame, which also preferablyacts as a journal for a sho-rt transversely disposed power shaft 14.This shaft 14 is in turn connected in a well-known manner to theposition shown in Y resilient pitman connection 3 by which the 1 isoperated. The

. connection 3.

As the fork is moved'back and forth by its power connection, it is alsodeflected laterally by means of a curved bail or guide 18 which isconnected to the fork through a plurality of rollers 19 disposed onopposite sides of the bail and moved with the fork. The bail 18 isdeflected alternately to one side or the other of the receptacle bymeans of a crank 20 and rotatable shaft 21, which is in turn connected,through a link 22, with the two to one gearing 23, 24 journaled on theframe at a point beneath the lshaft 4. In a preferred form the largergear 23 is carried on a suitable extension onthe bracket 15 hereinabovereferred to and driven from the shaft 14. This deflecting mechanismbroadly, however, forms no part of my present invention, being describedand claimed in my lastmentioned. -copending application.

As the sheaf delivery member 1 moves to the sheaf delivering position,it is also to be noted that it is controlled by springs after the mannerdescribed and claimed in my last mentioned application, one of thesprings herein which cushions its movement and gives it a backwardimpulse assuming thel form of a ycoiled spring 25 encircling the endofthe guide 18 and held in position thereon by a washer and cotter pin26. Obviously, the rollers 19 on the delivery member A1 will engage thewasher 26 and act to compress this spring each time that the fork swingsback to deliver a sheaf. In order to prevent bending of the crank 2,0byl this constant hammering, I. preferably also provide a plurality ofsuperimposed plates 27, both of which are connected betweenlongitudinally disposed supplemental frame members which act to carrythe shaft 4, the lupper of these plates 27 preferably being slotted at28 in such a manner as to permit the bail 18 to move in its arc when.

deflected by the two to one gear mechanism.

Coperating with the sheaf delivery member 1 and controlling thelcompressing, binding and discharging mechanism, is a size controlmechanism of the specific type described in mycopending application,Serial No. 743,740, iiledv January 23, 1913, comprising a cam 29 ofarcuate section disposed above the shaft 4 and normally having its upperand lower surfaces successively engagedby a Ymember 30 movable with thefork which, when the sheaves in the receptacle 6. have reached Vacertain height, through its power connections is obliged to movebackover the upper surface of the cam 29 into engagement with a normallyinoperative trip 31. Thistrip 31 is then operated and,`through a rod 32andspring connection 33, actuates a clutch controlling member 34. Inthis construction the clutch controlling member 34 is in the form of acrank, being substantially above the beveled gear 12,

where it is provided with a short rearwardly extending portion 36 and asecond grainwardly extending portion 37 whichV overlies a cam 38 formedon the knotter shaft.

As described in my irst mentioned copending application, and in amanner'` common to all shockers of this type, a clutch 39 is .providedon vtheshaft 14`which controls the movementof the fork 1. This clutch isprovided with a rotatable dog 40 and controls thepinions 23 and 24. Asecondclutch 41, having a rotatable clutch member or dog 42, is alsoprovided which controls the connection of the compressing, binding anddischarging mechanism of the shocker. `This clutch 41 is locatedslightly in rear ofthe beveled gear 13 upon a continuation of the shaft10 carrying that gear and, as shown, accomplishes the above -ends bycontrolling the connection of the knotter shaft9 to the power, which iscontinuously obtainable from the shaft 10 while the binder is in motion.

My improved clutch controlling mechanism acts to control both of Atheseclutch mechanisms throughjsuccessive engagements and dis'engagements` ofthe' rotary clutch members 40 and 42. When the member 43 is rocked aboutits pivot byl the deck trip 44 and the longitudinally Yadjustable rod45, as described in my c'opending application, Serial No. 801,527, filedNovember17', 1913; 2'. e., when a bundle passes overthe deck of thebinder, the rotating rclutch finger `40 of the fork clutch 39 isreleased, Va clutch from the path of the rotatable-clutch member 40 insuch a manner as to 'allow theV clutch 39 to connect the fork to thepower shaft. 14. The member 46, controlling the clutch, is slidablymounted in aV bearing 47, preferably formed in the bracket 15, Aand isprovided with a depressed portion 48 at its stubbleward end whichenables it to pass under another and coperating clutch controllingmember 49 disposed at an angle of about 45o with respect vthereto andpreferably connected to it by la spring 50. As shown, these two members46 and 49 are both of flat strap or bar construction and arereciprocably mounted in their supports, the member 49 preferably'movingthrough a slotted bearing similar to the slotted-bearing for the member46, and also-being provided with a similar'slotted bearing'in a support51 also preferably integral with the bracketr15 and adjacent the path ofthe clutch member 42, so that this member, when reciprocated, maysuccessively engage the rotating dogs 40 and 42. Pivotally mounted at apoint beneath the clutch controlling member 49l is a bell crank 52,having its free arm 53 protruding into an opening in the clutchcontrolling member 49, in which it preferably has a slight play, and itsother arm connected to a vertically disposed rod 54, which is in turnconnected to the crank member 34 at a point adjacent this laterallyextending portion 37.

Coperating with my improved controlling mechanism and driven from anysuitable intermittently movable part of the power mechanism; as, forinstance, the knotter shaft 9, is my improved dumping mechanism. Thismechanism replaces the upwardly swinging pivoted arm described inmycopending application, SerialNo. 573,106, filed July 21, 1910, which Ihave heretofore used to swing up underneath the shock receptacle andmove the same from its normal prostrate position to its vertical orshock discharging position. The new mechanism is illustrated in detailin Figs. '1, 2 and 6, wherein it -is to be noted that the receptacle 6is xed to the shaft 55 instead of rotating thereon, and is connected tothe knotter shaft through ak short crank 56 rotatably mounted ion theshaft 55, an upwardly extending link 57 pivoted t0 the crank 56, and asecond crank 58 iexibly connected to the upper end of the link 57 anditself rotatably mounted on the rear end of the knotter shaft9, a spring59 coiled about a sleeve 60 secured to the shaft 9 by a pin 91, whichpin, in addition to securing the sleeve to the shaft, extends outwardlythrough said sleeve, forming a projecting stud. One end of said spring59 is provided with a hook 591 positioned in the path of the lug 91, andthe other end of the spring is secured to the arm 58. The sleeve 60carries a laterally extending lug 601 which engages with the edge of thecrank arm 58 to rotate it during a portion of the revolution of theknottefr shaft 9 in such a manner as to raise and lower the link 57.

The operation of these parts is as follows: Upon the rotation of theknetter shaft 9 the sleeve 60 carrying the pin 91 is also rotated fromthe position shown in full lines Von Fig. 6 to a position approximately180 from its initial position, as shown by dotted lines in said figure.During this rotation the lug 91 contacts with the hooked end 591 of thespring 59 and puts saidspring under tension, and the laterallyprojecting lug 601 contacts with the edge of the crank arm 58, carryingsaid crank arm to the position indicated in dotted lines. At this pointin the revolution of the knotter shaft 9, the tension of the springbecomes sufficient to canry the crank arm 58 ahead of the lug 601 and toreturn said crank arm and the link 57 to the position shown in fulllines in Fig. v6.Y

`Secured to the shaft 55, and rotated in the path of the edge of thecrank 56 is a gagging member 61 engaged by said crank 56 when the crankis raised b-y the link 57. When the link v57 is returned to its normalposition |by the spring 59, the crank 56 will also Vbe lowered to its'full line position shown in Fig. 6. Obviously, as soon as each shock isset, the receptacle 6 will also be returned to its normal Vposition by alongitudinally disposed spring and chain connection 62 which isconnected between the receptacle 6 and a point at the front of theframe, a spring 63 connected to a longitudinally disposed rod 64coperating with this spring and also acting to cushion the receptacle asit returns to sheaf receiving position.

In the construction shown in Figs. 7 and 8, I have illustrated amodification of the binder clutch controlling mechanism, or size controlmechanism, described above, wherein, instead of using a camy of theconstruction shown in the preceding figures, a modified cam 65 isemployed, which is reversed as compared lwiththe cam 29, and has acooperating and correspondingly.V reversed tripping member 66, which isconnected to a clutch controlling member 67 having a depending crankthereon. In the use of this mechanism it is also necessary to reversethe p osition of the trip actuating member carbeing provided thereon, asshown, in order to cop erate with the reversed cam 65. The operation ofthis mechanism is, of course,-the same as thatdescriibed above. It willbe noted,'however, that this construction may, in certain way-s, beImade very much more compact than that which I have used heretofore, andthat it in certain ways also lends itself better to the problem ofproviding a mechanism which mc y not be broken during shipment.

In cooperation with the mechanism above described, it is, of course, tobe understood that I may, if desired, use any suitable fork retardingclutch 69 to eliminate the hammering and rebounding of the forkresulting from its increased speed of movement when returning to sheafreceiving position. This form of clutch is shown and described in detailin my copending application Serial No. 801,525, filed November 17, 1913.As shown, I also preferably use upstanding end tines 70 at the rear ofthe shock receptacle which are controlled by any suitable latch 71 sothat they are dropped rearward as the receptacle manner as tounderliethe shock butt, these tines being returned to their normalupstanding position after each shock is set, by means of a spring 72. Itis further obvious ried by the fork 1, an actuating member 68k 6 movesbackward in such a that if desired I' may also use any suitable i means,such as one or more upstanding tines 73, in the receptacle for'holdingthe sheaves in the receptacle in proper position duringthe building andsetting of the shock. In the use of the delecting bail 18 it is also tobe understood that the bail may also be mounted resiliently through asuitable connection 74 so that it may yield bodily laterallywhendesired. Similarly, if desired, a bundle stopping member or sheafsupporting member 7 5 may be disposed on the stubbleward side of thefork 1 when the latter is in sheaf receiving position in order to limitthe outward throw of thev bundles ejected from the binder deck. Thesemech- `to this connection the sheaves are ysuccessively delivered in thereceptacle 6 with their butts toward the rear, the fork 1 as itimovesrearward being deflected by the bail 18 so that it builds up a prostrateshock in which the sheaves have converging or overlapping` heads anddiverging butts. This operation will continue as the shock is `built up,with the clutch controlling member being reciprocated into and out ofengagement with the clutch dog 40 as the trip 44 is actuated by eachsheaf. IVhen, however, thesheaves in the receptacle 6 have reached acertain height; i. e., when the shock has reached a certain size, themember 30, which moves with the fork 1, will not be enabled to pass'over the entire surface of the cam 29 due to the fork striking thesheaves already in the receptacle. As a result, this member 30 will beobliged to pass backward over the same upper surface over which it' hasjust traveled instead of going into engagement with the under surface ofthe cani. In doing-this, it will trip olf the tripping member 31 and,through the rod and spring connection 82, 33, rock the crank 34 in itsbearings in Vsuch a 'manner as to raise the link 54. The upward movementof this link 54 will rock the bell crank 52 about its pivot and move theslidable clutch controlling member 49v stubblewardly in its bearings so'that its grainward end will be disengaged from the' rotating clutch dog42 andtits stubbleward end projected into the path of the clutch dog 40of the fork clutch. Obviously, as soon as the clutch dog 42 isdisengaged, the clutch 41 will connect the compressing, binding anddischarging mechanism tothe powershaft 10 for two revolutions, the cam38 on the knotter shaft rotating therewith in timed relation so as tohold the link 54 in its elevatedposition shown in also held out ofoperation during the oper-v ation of the compressing, binding anddumping mechanism. NVhen, however, the Clutch dog 42 has completed andstarted on its second revolution, the cam its first revolution` 38 willthen allow the crank member .36, 37

to drop down to the position shown in full lines i-n Fig. 5. This,through the springs 38 and 50,` will cause the bell crank 52 to berocked from the dotted line position shown in Fig. 5 to the full lineposition shown therein, thus withdrawing the stubbleward end of theclutch controlling member 49V from the dog 40 and the clutch dog 42.Obviously, withr the member 49 in this posi-tion, the rotation of thedog 42 will be arrested after the second revolution and the forkVmechanism will be free to operate when the next sheaf vin its movementover kthe trip 44 on the binderV deck causes the clutch controllingmember 46 toV be: again withdrawn. During this movement'it isy obviousthat the spring 50 will coperate with the two clutch members to assistin the clutch shifting operation. So far as the dumping mechanism isconcerned, attention is also directed `to the fact that when the knottershaft 9 is rotated, the gagging member 60 will also be rotated, carryingwith it the spring-pressed crank 58 in such a manner as to raise thesame vfrom the full line position shown in Fig. 6 to the dotted lineposition shown therein. raising movement of the crank 58 will cause asimilar raising movement of the link 57 and crank 56 and, through theengagement of this last mentioned crank with the gagging member or stop61 fixed to the shaft V55, will cause the rocking of that shaft aboutits pivot on the frame and the consequent dumping of the shock in theshock receptacle. It will be noted, however, that'when the crank 58 haspassed through slightly more than a half revolution, the spring 59 willthen come into play in such a manner as to take upor continuetherotation of the crank at a higher-speed, with theresult of disconnectingthe driving force and causing the parts to be returned to their normalfull line position illustrated in Figs. 2 and 6. Obviously, the rest ofthe mechanism will also be automatically returned to its initialposition in a well-known manner.

path of the rotating clutch projecting it into the path of f Thisv Y Itwill be noted that in my improved conshaft 14, through the vimprovedconnections provided, performs both the function of the long shaft andthe short shaft usually provided upon shockers of this type. It is alsoto be noted that by the provision of my improved controlling mechanism,the e011- struction is materially simplified from an assemblingstandpoint, substantially all of the work requiring accuracy in gagingand the like being required to be done upon the controlling mechanism,which, as shown, constitutes substantially a single unit, the variousparts, as shown, preferably being supported by a single casting. By thisconstruction practically fonly a single skilled operator is required inthe assembling of the machine in the factory, the rest of the work beingof a type which may be done by relatively unskilled labor. Otheradvantages of my improved construction will also be apparent to oneskilled in the art. Y

While I have in this application specifically described certain formswhich my invention may assume in practice, it is, of course, to beunderstood that these forms are used for purposes of illustration andthat the invention itself is not limited to embodiment in the same butmay be used in various other forms, all of which it is my intention toinclude within the scope of the appended claims.
